Referring to Fig. 1 of the drawings, 2 designates one of=thelegsorstandards support- 1ng a winding machlneofrthe usual gang ormultiple-unit type, and 3indicates the bed or frame on which the-windingunits are mounted. %The winding. mechanism ashereinillustratedt is of: awell known type comp'rising a (llLlIH OII drive-roll 5 and a rotatablecop-hold- 'ersor yarn-receiver 6 on which the package'is wound. Thecop-holder 6-is carried at the end of a swinging arm,indi'catedvgenerally upright9,

of a reciprocating thread-guide 10. The

to expedite thread-guidewldis mounted to slideon-h-ori- .7 zontal tracksor 'ways 111 and 12 and carries a roller or bowl 13 engaging a helicalgroove 14 in the rotating cam 15 from which it is reciprocated. Theconstruction of the winding mechanism as above indicated is well knownto those versed in the present art and is therefore not hereinillustrated in detail.

Each winding unit is usually provided with a tension-device for applyingresistance or tension to the draft on the yarn as it feeds to the cop orpackage being wound, and the present drawings illustrate a disk-tensionfor this purpose. In Fig. 1 the tension-device is shown as mounted on abracket 17 bolted to the front of the frame of the winding machine at 18and having a horizontal shelf or rest 19 supporting a vertical spindle20. A pair of opposite tension-disks 21 are mounted on the spindle 20with a weight-holder 22 slidable on the spindle thereabove and carryinga suitable number of weights 23 which apply pressure to hold thetension-disks against the strand of yarn drawing therebetween. Theweight-holder 22 is preferably arranged to bear against a spring 24coiled around the spindle 20, whereby a yielding pressure is exerted onthe upper tension-disk to press it down against the lower disk. Thestrand of yarn y is guided in an opening or guide-eye 26 at one side ofthe shelf 19 and draws across the top of the shelf to lead between thetwo tension-disks 21. From the tension-device the strand 1 draws througha suitable slub-catcher 27, as usually provided, and thence leads to thethread-guide 1O tobe fed therefrom and traversed thereby on the cop orpackage being wound.

In delivering yarn or other strand material from cops, bobbins and othertypes of headless packages the strand is usually drawn off over the endof the package, the supplies being arranged below the winding-units withtheir axes in line with the point to which the yarn delivers as it feedsthrough the tensiondevice. In the present application of the invention ahorizontal rod 28 is provided as a support for a plurality ofsupply-holders, the rod extending the length of the winding 1nachinewith its ends held in brackets 29 attached to the legs 2. As indicatedin Figs. 1 and 2, the brackets 29 are fastened to the web of the legs 2by means of clamps 30 secured in place by bolts 31, and the rod 28 isheld in hubs 32 at the ends of the brackets by means of set-screws 33,see Fig. 4.

It will be understood that a supply-holder is provided for each windingunit and the construction and arrangement of the present improved deviceis as next described. The main element of the holder consists of arotatable member constructed in the form of a hub or annulus 35 andprovided with a plurality of circumferentially disposed bosses 36drilled to I receive the radial spindles 37. Preferably, the bosses 36are tapered toward their outer ends to adapt them to enter the enlargedend of the bores in the bobbin-tubes b to center the bobbins on thespindles. The circular hub or annulus 35 is rotatable on a bearingmember40, see Fig. 3, secured fast A cap or disk 46 is fitted against the edgeof the rim 45 to retain the hub 35 in place on its bearing, the diskbeing fastened to the side of the member 40 by means of screws 47screwed into lugs orbosses 48 projecting from the side of the flange 43.Through the above described construction the hub or annulus 35 ismounted to rotate on the member 40 to bring the spindles 37 successivelyinto vertical position with their axes alined with the guide-eye 26 towhich the strand delivers as it feeds to the tension-device.

Means are provided for retaining the rotatable member or annulus 35 infixed position after each rotative movement thereof. As herein shownthis means consists of a detent-latch or pawl 50 which engages withsuitable depressions or slots 51 in the side of the hub 35. As apreferred form of construction the pawl 50, shown in enlargedperspective view in Fig. 5, is constructed from a strip of spring metalbent into shape to adapt it to be hooked through an opening 53 in theside of the plate or disk 46. The opening 53 is in the form of anelongated slot which is interrupted by a cross-piece 54 formed byslitting the metal at the sides of the slot and bending it outwardly inthe shape of a loop as shown most clearly in Fig. 4. The detent latch 50has a flat end 55 adapted to overlie the side of the disk 46, and beyondthis portion it is bent into a square-sided loop 56 which passes underpiece 54. Beyond the loop 56 the latch is inclined inwardly in a length57 having its end bent around in a toe-piece 58 adapted to engage withthe V-shaped grooves or slots 51 which provide ratchet-teeth or stops onthe side of the rotatable hub 35. Through the engagement of the toe 58of the pawl 50 with the grooves 51 the hub 35 is restrained fromunwarranted or accidental turning movement, but when it is required torotate the hub to bring a fresh bobbin into delivering position the pawlyields readily and rides along the face of the hub until it engages thenext succeeding groove.

The method of operation of the complete device is as next explained:Assuming that a bobbin B is in place on the uppermost spindle 37 withits alin-ed with the guide-eye 26 through which the strand ;2 feeds, asthe winding machine is operated the material is and around thecrossdrawn off from the bobbin and Wound onto the cop-holder 6 to buildthe desired form of r :its method of application.

As the winding proceeds and the supply of package.

yarn on the delivering bobbin becomes'de pleted the operator places afresh bobbin on the next forward spindle 37, just before the 4 end runsout on the first bobbin. As the last.

few coils of yarn are pulling off from the delivering bobbin theoperator shifts the fresh bobbin B into delivering position by turningthe supply-holder hub on its bearing 45. As the hub 35 is rotated thepawl rides out from the notch or groove 51 with which it is engaged andsprings into the next notch just as the new bobbin is brought intovertical position. The complete operation of placing the fresh bobbin onits spindle and adjusting it to delivering position may be effected bya'single manual movement, the operator impaling the bobbin on thespindle and pushing it upwardly With a circular mo tion of the hand.Meanwhile, the operation of the Winding machine is arrested by theaction of its automatic stopping-device as usually provided, and theoperator has only to tie up the end of the fresh bobbin with thetrailing end from the package, the spliced yarn being then drawn intothe tension-device and slub-catcher by the automatic threading action ofthese devices.

The operation of placing a fresh bobbin on the holder and adjusting itto delivering position as the end runs out on the spent bobbin isrepeated as becomes necessary during the Winding operation, and with thepresent improved device very little time is required for resupplying themachine with yarn.'

Each time a new bobbin is applied to the holder and turned intodelivering position the empty bobbin-tube or yarn-carrier Z) is carriedover to the right, as viewed in Fig. 2, and finally as it is turned intoposition with its spindle inclined downwardly, as

' represented by the dash lines in Fig. 1, the

empty tube 6 Will drop off from the holder to be cast into a suitablereceptacle or bobbinbox which may rest'on the floor at the front of themachine. As a consequence of the automatic doffing of the spent bobbinand the simple method of applying a fresh one in its place, the intervalduring Which the Winding is arrested is very brief and therefore ,7 theloss of production is materially reduced as compared with the-usualmethod where an exhausted bobbin must be first removed and a freshbobbin placed on the same spindle.

While the device is herein described and illustrated as embodied in apreferred form of construction, the structure and arrangement of itsparts may be varied at will without departing from the spirit or scopeof the invention Moreover, the improved device is susceptible of varioususes in transfer processes otherthan that herein described, and theinvention is therefore not limited as to What I claim' is: 1.A'supply-holder comprising a plural ityof means each adapted to hold abobbin,
